-* Actions Semi Owl Clock Management Unit (CMU)
-
-The Actions Semi Owl Clock Management Unit generates and supplies clock
-to various controllers within the SoC. The clock binding described here is
-applicable to S900, S700 and S500 SoC's.
-
-Required Properties:
-
-- compatible: should be one of the following,
- "actions,s900-cmu"
- "actions,s700-cmu"
- "actions,s500-cmu"
-- reg: physical base address of the controller and length of memory mapped
- region.
-- clocks: Reference to the parent clocks ("hosc", "losc")
-- #clock-cells: should be 1.
-- #reset-cells: should be 1.
-
-Each clock is assigned an identifier, and client nodes can use this identifier
-to specify the clock which they consume.
-
-All available clocks are defined as preprocessor macros in corresponding
-dt-bindings/clock/actions,s900-cmu.h or actions,s700-cmu.h or
-actions,s500-cmu.h header and can be used in device tree sources.
-
-External clocks:
-
-The hosc clock used as input for the plls is generated outside the SoC. It is
-expected that it is defined using standard clock bindings as "hosc".
-
-Actions Semi S900 CMU also requires one more clock:
- - "losc" - internal low frequency oscillator
-
-Example: Clock Management Unit node:
-
- cmu: clock-controller@e0160000 {
- compatible = "actions,s900-cmu";
- reg = <0x0 0xe0160000 0x0 0x1000>;
- clocks = <&hosc>, <&losc>;
- #clock-cells = <1>;
- #reset-cells = <1>;
- };
-
-Example: UART controller node that consumes clock generated by the clock
-management unit:
-
- uart: serial@e012a000 {
- compatible = "actions,s900-uart", "actions,owl-uart";
- reg = <0x0 0xe012a000 0x0 0x2000>;
- interrupts = <GIC_SPI 34 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&cmu CLK_UART5>;
- };

-This binding uses the common clock binding[1]. It assumes a
-register-mapped adjustable clock rate divider that does not gate and has
-only one input clock or parent. By default the value programmed into
-the register is one less than the actual divisor value. E.g:
-
-register value actual divisor value
-0 1
-1 2
-2 3
-
-This assumption may be modified by the following optional properties:
-
-ti,index-starts-at-one - valid divisor values start at 1, not the default
-of 0. E.g:
-register value actual divisor value
-1 1
-2 2
-3 3
-
-ti,index-power-of-two - valid divisor values are powers of two. E.g:
-register value actual divisor value
-0 1
-1 2
-2 4
-
-Additionally an array of valid dividers may be supplied like so:
-
- ti,dividers = <4>, <8>, <0>, <16>;
-
-Which will map the resulting values to a divisor table by their index:
-register value actual divisor value
-0 4
-1 8
-2 <invalid divisor, skipped>
-3 16
-
-Any zero value in this array means the corresponding bit-value is invalid
-and must not be used.
-
-The binding must also provide the register to control the divider and
-unless the divider array is provided, min and max dividers. Optionally
-the number of bits to shift that mask, if necessary. If the shift value
-is missing it is the same as supplying a zero shift.
-
-This binding can also optionally provide support to the hardware autoidle
-feature, see [2].

-Binding for TI mux clock.
-
-This binding uses the common clock binding[1]. It assumes a
-register-mapped multiplexer with multiple input clock signals or
-parents, one of which can be selected as output. This clock does not
-gate or adjust the parent rate via a divider or multiplier.
-
-By default the "clocks" property lists the parents in the same order
-as they are programmed into the register. E.g:
-
- clocks = <&foo_clock>, <&bar_clock>, <&baz_clock>;
-
-results in programming the register as follows:
-
-register value selected parent clock
-0 foo_clock
-1 bar_clock
-2 baz_clock
-
-Some clock controller IPs do not allow a value of zero to be programmed
-into the register, instead indexing begins at 1. The optional property
-"index-starts-at-one" modified the scheme as follows:
-
-register value selected clock parent
-1 foo_clock
-2 bar_clock
-3 baz_clock
-
-The binding must provide the register to control the mux. Optionally
-the number of bits to shift the control field in the register can be
-supplied. If the shift value is missing it is the same as supplying
-a zero shift.
